Abstract
The utility model discloses a heat exchanger unit, including the heat exchanger and with first medium inlet line, first medium discharging pipeline and second medium inlet line, the second medium discharging pipeline of heat exchanger cooperation setting, on first medium inlet line and the second medium inlet line, all be equipped with charge pump, first manual valve, reinforced bypass, air-entrapping pipeline in proper order, air-entrapping pipeline, including the air entrainment device and the first check valve that set gradually, between first medium inlet line and the first medium discharging pipeline, between second medium inlet line and the second medium discharging pipeline, all still be equipped with the overflow bypass. The heat exchanger unit of the utility model can lead the fed medium to flow away from the overflow bypass if the pressure is too high due to the blockage in the heat exchanger, thereby preventing the safety accident caused by the too high pressure of the heat exchanger; can provide the gas explosion function for when wasing, the bubble erodees heat transfer board wall and pipeline wall, and the cleanness is more high-efficient thorough, and the practicality is strong, is worth promoting.
Description
Technical Field
The utility model belongs to the heat transfer field especially relates to a heat exchanger unit.
Background
The current heat exchanger can be blocked due to heat exchange media, so that the pressure in the heat exchanger is too high, safety risks exist, in addition, when the heat exchanger is cleaned, cleaning liquid is mostly adopted for cleaning, but the cleaning efficiency is low, therefore, people hope to find a safer heat exchanger unit and have a more convenient cleaning mode.
SUMMERY OF THE UTILITY MODEL
To the technical problem, the utility model provides a heat exchanger unit.
In order to achieve the technical purpose, the utility model adopts the following technical scheme:
the heat exchange unit comprises a heat exchanger, and a first medium feeding pipeline, a first medium discharging pipeline, a second medium feeding pipeline and a second medium discharging pipeline which are arranged in a matched mode with the heat exchanger, wherein a feeding pump, a first manual valve, a feeding bypass and an air feeding pipeline are sequentially arranged on the first medium feeding pipeline and the second medium feeding pipeline, the air feeding pipeline comprises an air filling device and a first one-way valve which are sequentially arranged, and an overflow bypass is further arranged between the first medium feeding pipeline and the first medium discharging pipeline and between the second medium feeding pipeline and the second medium discharging pipeline.
Preferably, the feeding bypass comprises a second manual valve, a second one-way valve, a feeding tank and a third one-way valve which are arranged in sequence.
Preferably, a pressure valve is arranged on the overflow bypass.
Due to the adoption of the technical scheme, the utility model discloses following technological effect has:
the heat exchanger unit of the utility model is provided with the overflow pipeline, if the pressure is too high due to the blockage in the heat exchanger, the fed medium can be removed from the overflow bypass, and the safety accident caused by the too high pressure of the heat exchanger can be prevented; by arranging the feeding bypass, particularly the one-way valve, the flow direction of the medium is not changed, and the medicine is conveniently added without pressure; through setting up the gas supply pipeline, can provide the gas explosion function during for the washing, the bubble erodees heat transfer board panel wall and pipeline wall, and the cleanness is more high-efficient thorough, and the practicality is strong, is worth promoting.
Drawings
The invention will now be described, by way of example, with reference to the accompanying drawings, in which:
fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
